Step-by-step explanation:
I just know trust me
Answer:
Calculus
Step-by-step explanation:
Calculus: z = (94-70)/12 = 2
Bio: z = (74.5-77)/10 = -0.25
History: z = (45-53)/16 = -0.5
Physics: (70.5-60)/14 = 0.75
x = # of weeks
y = total amount of money
Your savings account: $122 + $12x = y
Your friend's savings account: $92 + $17x = y
As the question suggests, we need to set both equations equal to each other.
$122 + $12x = $92 + $17x
Subtract $92 from both sides and subtract $12x from both sides.
$30 = $5x
Divide both sides by $5
6 = x
It will take 6 weeks for you and your friend to have the same balance.
